Why do we need to add these here?

Because in this test config, this feature is specified with dns_zone_id. But in the import step, by default it will be imported as dns_zone_ids, so there're some differences between them.

This test will fail in 4.0 mode, so can we add a t.Skip for it?

@ms-henglu, this test as well as TestAccKubernetesCluster_webAppRouting will fail in 4.0 mode, can you please add the skip for these.
